The ABB CI532V02 3BSE003827R1 is a specialized and robust analog output module, an integral component of ABB’s highly regarded AC 800M High Integrity controller family, which forms the core of the System 800xA or Advant MOD 300 distributed control systems (DCS). This module, specifically the CI532 V2 model, is designed to deliver precise, reliable, and isolated control signals to final elements in safety-critical and high-availability process applications. Its primary function is to convert digital commands from the controller’s safety or process automation application into highly accurate, galvanically isolated analog current or voltage outputs (typically 4-20 mA). These outputs are used to drive field devices such as control valves, variable frequency drives (VFDs), I/P converters, or other actuators that require a continuous analog signal for precise positioning or speed regulation.
As part of the AC 800M HI (High Integrity) series, the ABB CI532V02 3BSE003827R1 is engineered to meet the rigorous demands of industrial environments where functional safety and maximum uptime are paramount. It plays a crucial role in safety instrumented systems (SIS) and critical control loops in industries like oil & gas, chemical processing, and power generation. The module features redundant power supply inputs and supports hot-swappable operation, allowing for maintenance or replacement without shutting down the entire control system. Its design emphasizes signal integrity and diagnostic capabilities, ensuring that any fault within the module or its connected loop is quickly detected and reported to the control system, enabling rapid response to maintain process safety and stability. The suffix 3BSE003827R1denotes the specific hardware revision and order code.

Key Features and Advantages
The ABB CI532V02 3BSE003827R1 excels through its combination of precision, robustness, and high availability. A core advantage is its high integrity and safety-oriented design. Engineered for use in safety loops, it features extensive internal diagnostics that continuously monitor the output stage, wiring integrity, and module health. Faults such as wire break (open circuit) or short circuit on the loop are detected and immediately signaled to the controller via the dedicated diagnostics communication, allowing for predefined safe actions to be taken. Its support for HART communication pass-through (when configured) enables advanced device management and calibration of smart field instruments without breaking the 4-20 mA control signal.
CI532V01
Maximum system availability is engineered into its operation. The module supports true hot-swappable replacement. A faulty module can be removed and a new one inserted into the powered baseplate without requiring a shutdown of the controller or other modules in the rack. The new module is automatically recognized, and its configuration is downloaded from the controller, minimizing process disturbance and maintenance downtime. The provision for redundant power supply inputs further enhances reliability by eliminating single points of failure in the power path. Each output channel is fully isolated, preventing faults or noise on one loop from affecting the other or the system backplane.
Seamless integration and engineering efficiency are key benefits within the 800xA environment. The module is fully supported by ABB’s Control Builder M engineering tool. Configuration, including scaling, fail-safe value setting, and HART parameterization, is performed graphically within the same project as the controller logic. This tight integration ensures consistency, reduces commissioning time, and simplifies maintenance. The front-accessible, removable terminal blocks make wiring and troubleshooting efficient and safe. For critical control and safety applications, the ABB CI532V02 3BSE003827R1 delivers the reliability, diagnostic depth, and maintainability required to protect personnel, the environment, and assets.
Application Areas
The ABB CI532V02 3BSE003827R1 is deployed in process automation scenarios where control loop reliability, accuracy, and safety are of utmost importance. Its primary application is within safety instrumented systems (SIS) and critical control loops across hazardous process industries. In oil and gas facilities, it is used to control emergency shutdown (ESD) valves, blowdown valves, and critical pressure control valves on offshore platforms, refineries, and LNG trains. Its precise output ensures valves move to their exact safe state upon demand.
In chemical and petrochemical plants, the module drives control valves for reactor temperature, distillation column pressure, or hazardous material flow rates, where precise control is essential for product quality and process safety. Within power generation, particularly in boiler control and turbine auxiliary systems, it provides the analog signals to regulate feedwater valves, fuel control valves, and turbine bypass valves. The module’s high availability features are crucial for minimizing unplanned outages. It is also found in pharmaceutical and fine chemical batch processes requiring precise dosing and recipe control, as well as in pulp and paper mills for controlling stock flow and chemical additives. Essentially, the ABB CI532V02 3BSE003827R1 is the interface of choice whenever a digital safety or control system needs to exert precise, reliable, and fail-safe analog control over a critical field element in a continuous process.
